"After being sure of good seed the next step to consider is when to plant the seed. It is well to start certain seed inside and so get a bit ahead of the season. Other seed may as well wait, and be planted out in the open when the ground is warm.
"Such vegetable seed as the following may be started inside.

"Flower seeds I will take up later because I wish to think over the flower garden by itself.
"When shall we plant seeds outdoors? Now no one under the sun can say plant such and such a seed on May 30th or April 1st. It is the same absurd case as saying change your winter clothes for summer ones on May 1st. Many writers will cover this subject by saying plant seeds when the earth is warm. But even that is a pretty general sort of direction.
"Nature has given us a planting guide. She tacks her notice on the fruit trees. When those early blooming trees, the peach and the plum, put out their beautiful blossoms the first planting time is on. To be sure the temperature then is a bit low, only about 45 degrees, so the planting is not of the more tender vegetables. Get your seed of beet, carrot, cabbage, cauliflower, endive, kale, lettuce, parsley, parsnip, onion, pea, radish, turnip and spinach. These may all be planted.
"The next signal to watch for is given by the blooming of the apple trees. This is the planting time for the more tender seed. These need a temperature of about 60 degrees in the shade, real apple-blooming time. Corn, beans, egg plant, melon, squash, cucumber, pumpkin, tomato and pepper seeds may be planted.
"But when is the time to put out the hotbed, or indoor-started seedlings? When the apple blossoms drop their petals and have passed by is the signal for them to go into the ground. Of course, they naturally would be the last, for they are made very tender from their glass-grown coddling.
"When it comes to the planting of seed there are certain things to remember always. First the ground should be made very fine. This is an easy matter if the planting is done in the hotbed, but more of a problem in the outdoor garden. It is foolish to plant at all if one does not intend to do things right. So work over the seed bed thoroughly. After all is fine and deeply worked, say to about a foot deep, the next thing to consider is this—how deep should a seed be planted?
